TELEGRAPH-SOUNDER.

:BPECIFIiC-ATICN forming part of Letters Patent No. 330,635, dated November 17, 1885.

Application filed May 11, 1885. Serial No. 165,040. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE W. STEWART, a citizen of the United States, and a resident of the city, county, and State of NewYork, have invented a new and useful Improvement in Telegraphic Sounders. of which the following is a specification.

My invention consists of a telegraph-sounder comprising magnets centrally located with regard to the baseboard and sunk beneath the base-board through apertures provided for their reception, and their lower end secured to the baseboard by a fixed yoke screwed to the under side of the base-board; a sounding bar or lever, operating with the armature pivoted just back of the magnets and having one arm passing between the magnets, with C-shaped jaws at its end forward of the magnets, adapted to engage with a soundingpost provided with a projection entering said jaws of the lever, so that the jaws will strike thereon as the lever vibrates. At the opposite end of the lever it is provided with a touch-point or pin, arranged to operate upward through an aperture in a casing or covering forming a rest to the operators fingers in receiving a message thereby through sense of touch as the lever vibrates, the lever being also provided with a regulating device by which it may be regulated to work more freely or otherwise, to suit the current, whether strong or weak.

It also consists in a sounding bar or lever attached to the armature and having C- shaped jaws at one end, and at its other end a pin or touch-point, as hereinafter more fully described.

In the drawings accompanying, Figure 1 is a vertical lengthwise section View. Fig. 2 is a plan View from above the entire instrument. Fig. 3 is a plan view of the bottom of the bed-plate, looking upward, showing the fixed yoke and wire connection.

A represents the bed-plate.

13 represents the armature, and G the magnet, with its connections for passing the current through it.

D represents the sounding-post, and D the projection.

E represents the hollow baseplate.

F represents the sounding-bar; G, the C- shaped jaw engaging with soundingpost projection by vibration at its one end, and H represents the touch-point or pin at its other end.

I represents the finger-rest over the point or pin H, and J the binding-posts.

K represents the post holding the pivot upon which the sounding lever or bar F operates.

M is the pivot, and L L regulate the throw of the sounding bar or lever.

N represents the regulator of the spring 0, which, by being tightened or loosened as to its pressure upon or against the sounding bar or lever F, serves to enable it to work more freely or otherwise, to suit the current, whether strong or weak.

1? is a fixed yoke supporting the magnet; Q, the usual wire-connections, and R the legs upon which the bed-plate stands.

S represents the fastenings underneath the bed-plate for the hollow base-plate; E and T, fastenings underneath for the binding-posts J, and W the fastenings for fixed yoke P.

\Vhat I claim as new, and desire to secure by Letters Patent of the United States, is

1. The telegraph-sounder comprising magnet G, sunk beneath the base-board A, and there fastened by a fixed yoke, P, the sound ing-post D, having a projection, D, the sounding bar or lever F, operating with armature B, and having C-shaped jaws Gat one end and the touch-point or pin H at its other end, arranged to operate through aperture I of the casing or covering I, and the regulating device, all arranged substantially as shown and described.

2. The sounding bar or lever F, attached to armature B, and having C-shaped jaws G at one end, and at its other end the pin or touch-point H, substantially as shown and described.

3. The combination consisting of the sounding bar or lever F, attached to the under side Signed at the city, county, and State of New of armature B, and having C-shaped jaws G, York, this 4th day of May, 1885.

magnets O, sunk into the bed'plate A and support-ed by fixed yoke P, sounding-post D, GEORGE W. STEWART. provided with projection D, and spring 0,

extending from post D to a knee formed in Witnesses:

the sounding-bar F, substantially as shown GEO. E. STEMMERMAN,

and described. JOSEPH H. NEWTON.
